Saving Miss Emma a former BR rescue

We were told that Emma has a cancer on her left front leg, An asperation has been done. Also the vet says it must be done very soon as there is not much skin in that area We are seniors and my husband works part time to get us food money, etc. His hours ave been cut so I've been suggested we do this. The bill is $541.32 If any dog lover out there PLEASE help us to raising this money. I wanted to have this sent directly  to the vet but they said they don't give out their account number. So I'm hoping with all my heart we can raise enough to give this girl a future Even a bit makes us closer to her surgery. Please give a pretty healthy girl a chance. Are there any NORTHWEST BOXER RESCUE family members that could help her? She is an alumni brought to use for a few reasons and of course we fell in love. Can anyone help? Ok. Thank you all for saving our rescues And of course saving Miss Emma!
